I asked infact what I need to provide because honestly I do not know.
Here is ceph -s:

It is a three server/osd test/evaluation system with Ceph and Proxmox PVE.
The load is very light and there is a lot of free space.
So:
- I NEVER had network issues. People TOLD me that I must have network
problems. I changed cables and switches just in case but nothing improved.
- One disk had bad sectors. So I added another disk/osd and then removed the
osd. Following official documentation. After that the cluster runned ok for
two months. So there was enough free space and the cluster has recovered.
- Then one day I discovered that proxmox backup was hanged and I see that it
was because ceph was not responding.

I said SSHD that is a standard hdd with ssd cache. It is 7200rpms but in
benchmarks it is better than a 10000rpm disk.
Thanks again,
Mario
